Preferably, the outer surface of the inner steel cylinder is provided with non-spiral tooth marks, the thread pitch is 10mm, and the depth of the tooth marks is 5 mm.
Preferably, the wedge-shaped opening transversely forms an included angle of 3.6 degrees with the cross section direction of the outer steel cylinder, the opening angle is 116 degrees, and the axial opening length is 110 mm.
Preferably, the opening angle of the wedge-shaped tooth shoe is 80 DEG degree
Preferably, the outer side of the wedge-shaped tooth tile is provided with an elastic steel sheet.
Preferably, the wedge-shaped tooth tile can rotate left and right in the wedge-shaped opening of the outer steel cylinder.
Compared with the prior art, the utility model, its advantage lies in:
1. the design that the inner steel cylinder and the outer steel cylinder are nested with each other is adopted, the adjustable and rapid telescopic function of the steel support is realized, and the effect of applying the prestress of the steel support stably is achieved;
2. the design of inclined wedge-shaped openings and wedge-shaped tooth tiles is adopted, the function of micro-adjustment of the steel support is realized, the control difficulty of the original construction tool during operation is reduced, and the pre-stress precision is improved.
